Can you help me out with a possible major decision?

Okay so kinda long story. I’ll try to keep it short and adding what I feel is the necessary details. My baby mama and I have been going on and off again for a couple years now and have been together (ish) for 4.5 years. Well I haven’t been feeling the same (love wise) as I was in the beginning and I can’t tell if it’s because I may have a crush on a co worker or because I’m not in love anymore. The girl at work is also in a relationship and has a daughter of her own. I should note that my baby mama and I have twin daughters. My coworker sometimes brings up her boyfriend but when she does it’s usually complaining of some sort. I can’t get a good read. At the beginning before we started to work with each other we would just catch each other staring and then quickly look away. I’m usually outgoing and talk to most people in the plant but I never strike up a conversation with her because of me being in a relationship and her being in one too. I noticed she talks to most people but never talked to me until we worked together (occasionally had a few minor interactions before then) while working together she tried to figure out my age (she did) she tried to guess my middle name (she got it) when I tried to guess hers I kept asking for hints but she wouldn’t give any and then said “geez all this just for a middle name” to her female friend worker. Occasionally our hands will touch and one time she pointed out, “I wonder how happy your girlfriend would be if I told her you touched my hand.” There’s a couple more examples but it’s already getting long. I can respond if needed but I’m just confused. I haven’t been feeling the same as the old times with my baby mama and don’t know if the crush is getting in the way or what and I don't know what my possible or not crush is feeling either. I’m very bad at reading people
